What does that have to do with "new server" As long as you are a new PLAYER, regardless of whether you are in a new SERVER, you will be at a disadvantage in Xserver stuff.
The difference is, if you are in a new server, at least you have a fair chance at sage, assuming there are enough people to run sage. Whereas if the new player joined an old server, he will be bullied in sage (and anything else PvP wise)
While I agree masuri matchmaking is problematic, what you are saying makes no sense whatsoever.
Actually, they're planning on making Sage x server as well...R.I.P
